To cti' evito/ire, i may conceit/t; n

@e it known that il, Geenen tmc-nnonn, s citizen et the llnlted States, and

resident oi Chicago, in the county of Cook end. State off illinois, have invented certo-in new and nseiinl improvements in Automatic Switches for Fleshers, dsc., of lwhich the following is e. "full, clear, and exect specifico.- tion.

El@ lilly. invention is concerned Vith automatic electric switch mechanism, designed primarily :tor iieshe'rs, as they are called, lout which may be employed tor other purposes, sind consists essentially of s pair oi magnets with e peil' oi associated switches end a 2@ cuit and simultaneously close another and vice verso., Y

To this end my invention consists in e certain novel structure end arrangement oi elements which Will be described et length in the body ot the speciicetion and the novel combinations particularly pointed out in the cleiins.

To illustrate my invention, l zinnen heie'to two sheets oi' drawings in whichl the seine n X n.1; reterence'cherecteifs are used to designate identical parte in all the figures9 Which- Figline 1 is n front elevation of the switch mechanism removed from the loil holding,` receptacle in which it is ordine-illy iinmersed; Fig. 2 is a similar `tieni in side ele- 'tation ot the seme mechanism; llfig. 3 is o iront elevation in sectiof. nfthe line ,lli-A of Fig, 2; l'ig. i is ,effdiegrcmnetic View showing the circuits;y and Elin'. 5 is o. similar d@ View, showing onev 'work circuit instead of the two shown in iig. d.

l have desif; my novel switch so that it is especially @dented-to operate in en oil iilled tank, in which it will be understood 45 to he immersed, although ll have not illustreted the tank.

' The various elements are located on en 'insnletingslsb 10, which is provided, with the ive binding posts 11, l2, 13, le and 15,

5@ et its upper end and the wire from the positive side lis connected to the post 1l and from the negative side to the post 12. ll'here the switch is need es a flasher for the two sets, ci lamps, es indicated in Fig. 4, ille m est will he connected to the positive sido of one set of lamps i3, while the post will lloe connected to the positive side of another set ot lamps 17, and e common return Wire in that case will be connected to the post 12 by the wire 19. 'lhe binding posts 20 and 2l ere electrically connected to the switch contacts 22v and 23 end where it is connected there will be two ot er bindin posts 24 an 25 connected with the switc contacts 26 and 27'. 'lhe binding post 11 is connected by the wire 28 with the post 20, which in turn is connected by the Wire 29 with the binding post 2li., The binding ost 21 is connected by the wire 30 with t ie'binding post lll, while the binding ost 25 is 'connected by the wire 3l with t e binding. post 15. A switch having two blades 32 and 33 is pivotelly mounted upon the standards 34 and 33 are adapted to engage the contacts 22 and. 23 while ythe lower ends of the blades ere adapted to engage. the. contacts connected in any desired manner as by the three spacing rods 33, 3? and 38,' and it will 'be readily apparent that whenthe upperfend switch blades 32 :nud33 are in engage lent with the contacts 22 and 23,'the'crcui ,will be closed from the positive mainthliough the contact 22, switch contact e, Contact lil, the lompe 16, returnf-vire 18, Contact i3, Wire 19, and contact-l2 to'thc negative moin. When the A'switch is -inthe other position, es indicated-"in the "dotted lines in Fig. 2, the circuiti, will be closed through the contacts 24 and 25, wire 31, contact 15, lamps 17 and return Wire 18 as before.

To control the :iutornatic operation of this switch Where the device is used as a flasher,

lowing device: Suitehly supporte from the base piece l() by the lugs 29a and 40 are a peir of solenoid magnetsv 39 and 40, which are shown in axial e'linement end preferably have the single supporting tube l1- shown with the three flangesforming, as itw/ere, two spools. 'lhe moin core l2k ol'the lower solenoid is preferably e heavy metal rod and carries on the lower end thereof the piston 13, adapted to cooperate with the dash pot up for two circuits iis-indicated in Fig.

26 end 27. rlhe two blades are electrically.-

so that first one circuit will be closed for 3 7 time and then the other, l emplo the fol- 18 may be connected to the negative side of?V both sets o lamps and to the post 13, which and 35, and the upper ends ofthe blades 321,
